Title: cam sync rule....is this true?
Post by: krzak on June 20, 2010, 08:17:35 PM
Hello
I installing vems in 4cyl car with 2 long teeth on crank and 1 tooth on cam.
I have no spark :(

I use FW 1.1.18

I heard rule about cam sync "The only rule is that you can't have a second trigger pulse at the same time as a crank trigger pulse"

Is this true?

What with new FW ie.1.1.70?
I always must use this rule to cam sync?
When it will be change?

Thx for learn :)

This config uses the same trigger setup, and runs. Right now I recommend firmware 1.1.74.
